How to get both value and label of SelectControl?

Question

I am trying to get both the value and label in a SelectControl.

If I do:

<SelectControl
    label={ __( 'Content Type' ) }
    value={ contenttype }
    options={ contenttypeControlOptions }
    onChange={ ( selectedContentTypeOption ) => {
        props.setAttributes( {
            contenttype: selectedContentTypeOption,
            contentlabel: ?,
        } );
    } }
/>

I get the value just fine. But how to set the label as well? I thought the variable selectedContentTypeOption would be an object for the selected item but it is just a string for the option value. I am new to React so perhaps there is something obvious I am overlooking!
